Breath.
In one embodiment, geometry state measurement instrument can be used to detect static track geometric data, energy
Obtain height, rail to, gauge, level, distortion, superelevation, gauge change rate, plane coordinates and elevation (left rail, middle line, right rail) etc.
Inside and outside portion's geometric parameter of track etc..And in embodiments of the present invention, " shape information for obtaining static track geometric data " refers to
It is the shape information for obtaining a certain or several parameter in above-mentioned parameter, for example, the shape information of available " height ".
Step 102 is filtered using shape information of the high-pass filter to the static track geometric data, is obtained dynamic
Morphotype intends Wave data.
It should be noted that the wavelength components of detection data are different under dynamic and static state, i.e., examined in static device
Under survey, wavelength components are more complex, comprise more than dynamic detection long wave cut-off wavelength 120m irregularity ingredient, and in dynamic detection
In, comprising the medium wave irregularity of wavelength components 1.5m~42m and the long wave irregularity of 1.5m~120m, and field operation and data
Medium wave irregularity is mainly applied in analysis.
Since high-pass filter is that a kind of frequency allowed higher than a certain cut-off frequency passes through, and is greatly attenuated the filter of lower frequency
Therefore wave device can be filtered the long wave irregularity in shape information by using high wave filter, obtain dynamic analog waveform
Data dynamic analog Wave data.
Step 103 optimizes processing to high-pass filter, and the phase characteristic of the high-pass filter is made to meet linear phase
Position condition, and obtain the transmission function with the consistent dynamic analog Wave data of dynamic detection train.
Based on step 102, in order to make the phase characteristic of high-pass filter meet condition for linear phase, and dynamic analog is obtained
The transmission function of Wave data needs to optimize high-pass filter processing, as an example, can be to high-pass filter
Windowing process is carried out, and in order to improve effect of optimization, when carrying out windowing process, the window added can be in parallel or cascade rectangle
Window.
It should be noted that also will do it corresponding filtering when comprehensive detection train dynamic detection track geometry and generate
Transmission function, therefore the transmission function formula that the embodiment of the present invention obtains is consistent with when comprehensive detection train filtering, thus
Dynamic detection data can be finally inversed by when bandpass filtering.
If not meeting condition for linear phase after carrying out windowing process, it is also necessary to carry out adding window again.
Wherein, transmission function are as follows:
Wherein, z is the amplitude after transform, and k is cutoff wavelength, m=0.829k, n=0.646k.
Cutoff wavelength refers to the wavelength of a section, such as this section of wavelength of 1.5-42m.
Step 104 is filtered using transmission function result of the bandpass filter to dynamic analog Wave data, is obtained anti-
Drill dynamic data.
Since high-pass filter can filter the long wave irregularity in shape information, in order to further by shortwave
Irregularity filters, and the final medium wave irregularity obtained in shape information successfully completes dynamic data inverting, can be used at this time
FIR bandpass filter.
Dynamic data inversion method provided in an embodiment of the present invention, by carrying out the inspection of static track geometric data to track
It surveys, obtains the shape information of static track geometric data, and using high-pass filter to the wave of the static track geometric data
Shape information is filtered, and obtains dynamic analog Wave data；Processing is optimized to the high-pass filter, filters the high pass
The phase characteristic of wave device meets condition for linear phase, and obtains the transmission function of dynamic analog Wave data；Utilize bandpass filtering
Device is filtered the transmission function result of dynamic analog Wave data, inverting dynamic data is obtained, preferably by static track
Geometric data associates with dynamic data, is estimated using static detection data to dynamic detection effect, can save big
Manpower and material resources cost is measured, the activity duration is shortened, improves operating efficiency.

Filter in detection system can not be identical；(2) dynamic detection be have carry in the state of carry out, static detection be
It is carried out in the state of no-load, when being detected when having and carrying, some deformation twocomponent signal such as track plates of track structure
Wavelength components can enter in signal, and for details, reference can be made to the dynamic and static weighing data frequency domain comparison diagrams of attached drawing 7.
Although there are fine differences in individual places, relevant standard is referred to, still can satisfy that " rail detection system is provisional
Technical conditions " specified in same rail detection system 95 percentiles of difference value will meet less between detection data twice
In 1mm, about herein, reference can be made to the cumulative distribution figure of attached inverting data shown in Fig. 8 and measured data difference value.

Attached drawing 10.
Then, it by after the calibration of dynamic detection data mileage, is compared with static inverting waveform, comparing result can be found in attached
Figure 11.
It can be seen from figure 11 that static inverting data are essentially coincided with the actually detected data of dynamic, only individual places are deposited
In small difference, this is mainly due to mileage deviations and synthetic detection vehicle to be in the environment of electromagnetic interference.But from waveform
From the point of view of the goodness of fit and correlation, inversion result can satisfy the application of Practical Project.

The dynamic detection waveform that synthetic detection vehicle is surveyed when with static detection time phase difference 16 days is as shown in Fig. 14, can
To find out, dynamic detection mileage and practical mileage have certain deviation, and departure is about in 11m or so.
Then, it by after the calibration of dynamic detection data mileage, is compared with static inverting waveform, comparing result can be found in attached
Figure 15 and attached drawing 16.
From attached drawing 15 and attached drawing 16 as can be seen that static inverting data are essentially coincided with the actually detected data of dynamic, only
Individual places are there are small difference, this may be since sound state detection time is inconsistent, and synthetic detection vehicle is in electromagnetism
Caused by the environment of interference, but phase residual quantity, all in the range of 1mm, the margin of error meets the required precision of synthetic detection vehicle.Again
From the point of view of the goodness of fit of waveform, inversion result can satisfy the application of Practical Project.
Other parameters such as gauge, level, twist irregularity are all absolute measurements, and the measuring principle of sound state is almost the same, itself
It does not need to carry out inversion algorithm, it is only necessary to be calculated according to corresponding base length, then interpolation, such as attached drawing 17, attached drawing 18
It is shown.
To sum up, it is found that parity inversion result after being verified using the application to route A, route C, route B real data
Correctly, it can satisfy the practical application of engineering, it therefore, can be well by static track geometric data and dynamic using the method
Data associate, and realize the general of evaluation criterion, not only realize the static evaluation of accurate adjustment effect, also predictable static effects
